We have a system where you can purchase seats in classrooms. We have a good way of checking if seats exist at checkout but we want to implement a "reservation" system where a user "reserves" a seat when they add it to their cart but it doesn't actually "purchases" the seat until they checkout.

In doing this we want to implement a timer where we can notify them if they went over the limit. How would I be able to do this using javascript if they decide to venture off the cart page?
Is there any way for us to "remember" the timing for that customer? I know places like TicketMaster does this sort of thing but how do they implement it?

Our backend is PHP. We communicate to Oracle through a .Net webservice using the nuSoap classes in our PHP scripts.
